babel-plugin-jsx-wrapper

Automatic decorate jsx arrow functions for smartify and purify your code 👍

That plugin for babel wraps all not wrapped arrow functions (that contains JSX and defined in file global scope) to decorator function with easy configuring Remini, Mobx, and Realar (but possible for configure to custom one). Less code more effectiveness!

Remini

import { box, read, update } from 'remini';
/* import { component } from 'remini/react'; */

const $value = box(0);
const next = () => update($value, (v) => v + 1);

// const App = component(() => {
const App = () => (
  <>
    Ticker: {read($value)}
    <br />
    <button onClick={next}>Next</button>
  </>
);

See wrapped version on CodeSandbox.

You are no need more to wrap (decorate) JSX components to component function! It will be automatic.

// .babelrc.js
module.exports = {
  "plugins": [
    ["jsx-wrapper", {
      "decorator": "remini-react" // "remini-preact", "realar", "mobx-react", "mobx-react-lite", or some custom
    }]
  ]
};

Mobx

import { makeAutoObservable } from 'mobx';
/* import { observer } from 'mobx-react-lite'; */

class Ticker {
  value = 0;
  next = () => this.value += 1;

  constructor() {
    makeAutoObservable(this);
  }
}

const ticker = new Ticker();

// const App = observer(() => (
const App = () => (
  <>
    Ticker: {ticker.value}
    <br />
    <button onClick={ticker.next}>Next</button>
  </>
);

See wrapped version on CodeSandbox.

// .babelrc.js
module.exports = {
  "plugins": [
    ["jsx-wrapper", {
      "decorator": "mobx-react-lite" // "mobx-react", "remini-react", "remini-preact", "realar", or some custom
    }]
  ]
};

        "src/components/*",
        "src/pages/*"
      ],
